Locking an entire class notebook section.

Hi,

I teach undergraduate design students. During our recent move to online teaching, I have started to use OneNote as a digital alternative to hard copy sketchbooks. Students have been adding progressive sketches by adding relevant pages to their respective class notebooks. I would like to know if there is an option of locking the entire class notebook. I am aware that there is an option of locking a distributed page. This option would not work for me.

 

Thank you in advance.
